ELEMENT D'OBTURATION ET D'ANCRAGE DENTAIRE PREFABRIQUE EN MATERIAU COMPOSITE RADIO OPAQUE ET TRANSLUCIDE

摘要

Dental filling material (A), of composite material (M) and intended for gluing into a cavity or dental canal, using a glue (B) that can be polymerized by photochemical initiation. Dental filling material (A), of composite material (M) and intended for gluing into a cavity or dental canal, using a glue (B) that can be polymerized by photochemical initiation. (M) comprises a resin-based matrix reinforced by fibers (11) and particles (12) so that it is radio-opaque but transparent to light, forming a light conductor. The new feature is that (12) are made from a base material (M1) that is naturally opaque and has a particle size close to 1/4 of the wavelength (lambda ) of the light being used for polymerization of (B).
